Comments:
Segment is located in narrow valley bounded on either side by till covered, bedrock-core slopes. Valley is narrowed somewhat by encroachment of Kansas Rd and Prouty Hill Rd along RB, as well as historic mill development, along RB. Reference "Broad" valley is reduced to "Narrow" confinement. Channel-spanning bedrock is exposed near upstream end of segment (and frequently in the downstream segment A). Channel flows along LB valley wall upstream of Prouty Hill Rd culvert crossing and is incised (historically) below the RB floodplain. IR of 2.5 lead to STD classification (C to F). Remnants of possible dam noted in vicinity of upstream channel spanning bedrock. Possible former A. Wallace clothes pin factory (Beers, 1869). Nearby foundation remnants are coincident with RB near upstream end of segment and comprise a section of "Hard Bank" armoring which continues as rip-rap downstream to Prouty Hill Rd crossing. Driveway leading to old mill foundations along RB is not significantly elevated above floodplain surface. Prouty Hill crossing is arch-pipe culvert with bankfull-constricting span; scour pool has developed below the culvert. Straightening is inferred within the segment due to linear planform, historic impoundments and encroachments. Stormwater input (road ditch runoff) was documented along LB near downstream end of Prouty Hill Rd culvert.
